Vedclass · Answer

(D) Hofmann bromamide degradation of $CH_3CONH_2$ yields methylamine $(CH_3NH_2)$,a primary amine.$(b)$ Curtius rearrangement of $CH_3COCl$ with $NaN_3$ followed by hydrolysis yields methylamine $(CH_3NH_2)$,a primary amine.$(c)$ Reduction of $CH_3CH_2CONH_2$ with $LiAlH_4$ yields ethylamine $(CH_3CH_2NH_2)$,a primary amine.$(d)$ Reduction of methyl isocyanide $(CH_3NC)$ with $LiAlH_4$ yields dimethylamine $(CH_3NHCH_3)$,which is a secondary amine.Therefore,the correct option is $(d)$.
